Description

Technical Field

[0001] The present invention relates to the technical field of wire harness welding equipment, and in particular to a wire harness welding intelligent robot and a use method thereof. Background Art

[0002] A wire harness is an integrated system consisting of multiple wires, connectors, insulating materials, etc. It is mainly used to transmit power or signals. The purpose of wire harness welding is to ensure the stability of the electrical connection between wires and connectors, terminals and other components. They use heating or pressurization, or both, to combine the workpieces.

[0003] Among them, when welding the wire harness, in order to maintain the stability of the wire harness during welding, the wire harness often needs to be clamped. When clamping a wire harness with a larger diameter, a larger clamping force is usually required. A larger clamping force may cause the wire harness to be over-compressed, especially for wire harnesses with multiple wires, which may cause the wires to be misaligned, affecting the position of the wires and the precise positioning of the wires by the welding robot during welding. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a wire harness welding intelligent robot, comprising a welding table and a welding robot, wherein two electric telescopic rods are fixedly connected to the top of the welding table, two clamping blocks are arranged on the top of the welding table, the outer walls of the two clamping blocks are fixedly connected to fixed plates, the side walls of the two fixed plates are fixedly connected to the output ends of the side walls of the electric telescopic rods, the top of the welding table is slidably connected to a wire harness, the top of the welding table is fixedly connected to a placement plate, and the parts contained in the two clamping blocks are the same;

[0005] A suction mechanism, the suction mechanism includes a sliding ring slidably connected to the inner wall of the clamping block, a spring connecting rod slidably connected to the inner wall of the clamping block, a side wall of the spring connecting rod is fixedly connected to the side wall of the sliding ring, nine suction cups are fixedly connected to the side wall of the clamping block, a push plate is slidably connected to the inner wall of the clamping block, a spring reset rod is fixedly connected to the side wall of the push plate, an outer wall of the spring reset rod is slidably connected to the outer wall of the clamping block, and a dust removal component is provided on the outer wall of the clamping block;

[0006] The blocking mechanism comprises a fixed arc block fixedly connected to the inner wall of the clamping block, a sliding arc block is slidably connected to the inner wall of the clamping block, an arc spring is fixedly connected to the side wall of the sliding arc block, three connecting grooves are provided on the inner walls of the fixed arc block and the sliding arc block, and a guiding assembly is provided on the outer wall of the clamping block. The staff places the wiring harness to be welded on the welding table, inserts the multiple wires in the wiring harness into the placement plate, and then starts the electric telescopic rod to extend, pushes the fixed plate to move in the direction of the wiring harness, drives the clamping block to move, and makes the two clamping blocks approach each other. When the clamping block moves, it will drive the spring connecting rod to move. As the clamping block continues to move, the two spring connecting rods will contact each other, so that the two spring connecting rods are squeezed against each other, and the two spring connecting rods are moved away from each other, driving the sliding ring to move, and at the same time, allowing the two spring connecting rods to accumulate rebound force. At this time, since the connecting grooves on the fixed arc block and the sliding arc block are intertwined and not yet connected, when the sliding ring moves, it will make When the two push plates are in contact with each other, the two push plates will squeeze each other, causing the two push plates to move away from each other. At the same time, the spring reset rod will accumulate resilience. When the push plates move away from each other, the push plate will push the sliding arc block to slide in the clamping block, thereby moving the sliding arc block and squeezing the arc spring. When the sliding arc block moves, the connecting groove on the fixed arc block will be connected to the connecting groove of the sliding arc block, and the negative pressure will be transmitted to the suction cup through the connecting groove, thereby allowing the suction cup to adsorb the wire harness and complete the clamping of the wire harness. After the clamping is completed, the welding robot is started to weld the wire harness. By adsorbing and clamping the wire harness, uniform adsorption force is provided, which effectively prevents the wire harness from being subjected to excessive extrusion force during the clamping process, avoids the misalignment of the wires inside the wire harness, and affects the position of the wires, so that the welding robot can accurately locate the position of the wires in the wire harness.

[0007] Preferably, the dust removal assembly includes a fixed ring fixedly connected to the outer wall of the spring connecting rod, two inclined rods fixedly connected to the side wall of the fixed ring, two fixed frames fixedly connected to the outer wall of the clamping block, and spring extrusion plates slidably connected to the inner walls of the two fixed frames. When the two spring connecting rods move away from each other, the fixed ring will also be driven to move, allowing the inclined rod to move. As the inclined rod continues to move, the inclined surface of the inclined rod will contact the inclined surface at the top of the spring extrusion plate, thereby squeezing the spring extrusion plate, causing it to drop, accumulating rebound force, and at the same time, squeezing the gas in the fixed frame.

[0008] Preferably, the dust removal assembly also includes an inclined panel fixedly connected to the bottom of the spring extrusion plate, and the inner walls of the two fixed frames are slidably connected with the spring inclined panels. The bottoms of the two fixed frames are connected with air pipes. At this time, the squeezed gas will be blocked by the spring inclined panel, so the gas pressure will increase. When the spring extrusion plate descends, the inclined panel will also be driven to descend, so that the inclined surface of the inclined panel will contact the inclined surface of the spring inclined panel, thereby squeezing the spring inclined panel.

[0009] Preferably, the dust removal assembly also includes two air collecting frames fixedly connected to the outer wall of the clamping block, and the side walls of the two air collecting frames are through-connected to the outer wall of the air pipe. The two air collecting frames are through-connected on the side away from the air pipe. The spring inclined panel moves toward the air collecting frame, thereby eliminating the obstruction to the gas. The gas will enter the air pipe, be transported into the air collecting frame through the air pipe, and be dispersed into the jet pipe through the air collecting frame. At this time, since the suction cup is not in contact with the wire harness, the gas will be sprayed toward the wire harness through the jet pipe 1 to remove the dust attached to the wire harness.

[0010] Preferably, the guiding assembly includes a sliding ring slidably connected to the outer wall of the clamping block, the tops of the two spring extrusion plates are fixedly connected to a connecting frame, the outer wall of the clamping block is rotatably connected to two rotating frames, the inner walls of the two rotating frames are slidably connected to the side walls of the connecting frame, and the side walls of the sliding ring are slidably connected to the inner walls of the two rotating frames. When the spring extrusion plate descends, the connecting frame will also be driven to descend, the rotating frame will descend, the rotating frame will rotate, the rotating frame will tilt, and the sliding ring will be pulled to move toward the fixed frame.

[0011] Preferably, the guide assembly further comprises four racks fixedly connected to the outer wall of the sliding ring, the inner walls of the two gas collecting frames are rotatably connected to two gear rods, the side walls of the four racks are meshed and connected to the outer walls of the gear rods, the outer walls of the four gear rods are fixedly connected to fan-shaped frames, and the side walls of the two gas collecting frames are fixedly connected to two fixing rings;

[0012] Among them, the inner walls of the four fixed rings are fixedly connected with clockwork springs, and the inner walls of the four clockwork springs are fixedly connected to the outer wall of the gear rod, driving the rack to move, allowing the rack to mesh with the gear rod, driving the gear rod to rotate, allowing the fan-shaped frame to rotate, and allowing the clockwork spring to rotate, so that the clockwork spring is tightened and accumulates rebound force. When the gas in the fixed frame enters the gas pipe, the rack will separate from the gear rod, the limit on the clockwork spring will disappear, and the rebound force of the clockwork spring will be released, allowing the fan-shaped frame to rotate, thereby guiding the airflow entering the gas collecting frame.

[0013] Preferably, the guide assembly also includes three jet tubes 2 connected through the inner wall of the clamping block, the inner walls of the three jet tubes 2 are rotatably connected with blocking rings, the side walls of the sliding ring are fixedly connected with three fixing rods, and the outer wall of the clamping block is fixedly connected with three spring blocks. When negative pressure is generated on the side of the sliding ring close to the fixed arc block, the sliding ring will also squeeze the gas on the side away from the fixed arc block, and the squeezed gas will enter the jet tube 2 and be blocked by the blocking ring, so that the gas generates high pressure. At the same time, when the sliding ring moves toward the fixed frame, it will also drive the fixed rod to move, so that the fixed rod contacts the blocking ring, push the blocking ring to rotate, and squeeze the spring block. When the blocking ring rotates, the gas in the jet tube 2 is blocked, so that the high-pressure gas is sprayed toward the surface of the clamping block close to the wiring harness and the suction cup, thereby accelerating its cooling speed.

[0014] A method for using a wire harness welding intelligent robot comprises the following steps:

[0015] S1: adsorption clamping;

[0016] S2: dust removal;

[0017] S3: Airflow guidance.

[0018] The present invention has the following beneficial effects:

[0019] (1) When the present invention is used, the staff places the wire harness to be welded on the welding table, inserts the multiple wires in the wire harness into the placement plate, and then starts the electric telescopic rod to extend, pushes the fixed plate to move in the direction of the wire harness, drives the clamping block to move, and makes the two clamping blocks approach each other. When the clamping block moves, it will drive the spring connecting rod to move. As the clamping block continues to move, the two spring connecting rods will contact each other, so that the two spring connecting rods are squeezed against each other, and the two spring connecting rods are moved away from each other, driving the sliding ring to move. At the same time, the two spring connecting rods accumulate rebound force. At this time, because the connecting grooves on the fixed arc block and the sliding arc block are staggered and not yet connected, when the sliding ring moves, negative pressure will be generated on the side of the sliding ring close to the fixed arc block. As the clamping block continues to move, the two pushing plates will also contact each other. At this time, the suction cup will also When the two push plates are in contact with the surface of the wire harness, the two push plates will squeeze each other, allowing the two push plates to move away from each other. At the same time, the spring reset rod will accumulate rebound force. When the push plates move away from each other, the push plates will push the sliding arc block to slide in the clamping block, thereby allowing the sliding arc block to move and squeeze the arc spring. When the sliding arc block moves, the connecting groove on the fixed arc block will be connected to the connecting groove of the sliding arc block, and the negative pressure will be transmitted to the suction cup through the connecting groove, so that the suction cup can adsorb the wire harness and complete the clamping of the wire harness. After the clamping is completed, the welding robot is started to weld the wire harness. By adsorbing and clamping the wire harness, uniform adsorption force is provided, which effectively prevents the wire harness from being subjected to excessive extrusion force during the clamping process, avoids the misalignment of the wires inside the wire harness, and affects the position of the wires, so that the welding robot can accurately locate the position of the wires in the wire harness.

[0020] (2) When the two spring connecting rods of the present invention move away from each other, the fixed ring will also be driven to move, so that the inclined rod will move. As the inclined rod continues to move, the inclined surface of the inclined rod will contact the inclined surface at the top of the spring extrusion plate, thereby squeezing the spring extrusion plate, causing it to descend and accumulate rebound force. At the same time, the gas in the fixed frame will be squeezed. At this time, the squeezed gas will be blocked by the spring inclined plate, so the pressure of the gas will increase. When the spring extrusion plate descends, it will also drive the inclined plate to descend, so that the inclined surface of the inclined plate contacts the inclined surface of the spring inclined plate, squeezing the extrusion spring inclined plate, and causing the spring inclined plate to move toward the gas collecting frame, thereby eliminating the obstruction to the gas. The gas will then enter the gas supply pipe, be transported into the gas collecting frame through the gas supply pipe, and be dispersed into the injection pipe through the gas collecting frame. At this time, since the suction cup is not in contact with the wiring harness, the gas will be sprayed toward the wiring harness through the injection pipe, and the dust attached to the wiring harness will be removed, effectively preventing dust from being attached to the wiring harness, which may affect the close fit between the suction cup and the wiring harness and the adsorption effect of the suction cup.

[0021] (3) When the spring extrusion plate of the present invention descends, it will also drive the connecting frame to descend, allowing the rotating frame to descend, rotating the rotating frame, and tilting the rotating frame, pulling the sliding ring to move toward the fixed frame, driving the rack to move, allowing the rack to mesh with the gear rod, driving the gear rod to rotate, allowing the fan-shaped frame to rotate, and allowing the clockwork spring to rotate, allowing the clockwork spring to tighten and accumulate resilience. When the gas in the fixed frame enters the air delivery pipe, the rack will separate from the gear rod, the limit on the clockwork spring will disappear, the resilience of the clockwork spring will be released, and the fan-shaped frame will rotate, thereby guiding the airflow entering the air collecting frame, and the airflow will be attracted to the top and bottom jet pipes 1, so that the gas entering the three jet pipes 1 is evenly distributed, effectively preventing most of the gas from being ejected from the jet pipe 1 in the middle, affecting the removal of dust on the surface of the wire harness, and may make dust in some areas difficult to remove.

[0022] (4) In the present invention, when negative pressure is generated on the side of the sliding ring close to the fixed arc block, the sliding ring will also squeeze the gas on the side away from the fixed arc block. The squeezed gas will enter the second jet tube and be blocked by the blocking ring, causing the gas to generate high pressure. At the same time, when the sliding ring moves toward the fixed frame, it will also drive the fixed rod to move, causing the fixed rod to contact the blocking ring, pushing the blocking ring to rotate and squeezing the spring block. When the blocking ring rotates, the gas in the second jet tube is blocked, allowing the high-pressure gas to spray toward the surface of the clamping block close to the wire harness and the suction cup, thereby accelerating its cooling speed and effectively preventing the high temperature generated during the welding of the wire harness from being transferred to the clamping block. In addition, due to the high welding speed of the welding robot, the temperature of the clamping block and the suction cup may continue to rise and be difficult to effectively cool down, resulting in temperature accumulation, which may cause the suction cup to have a poor adsorption effect on the wire harness, thereby helping the suction cup to maintain a good adsorption effect for a long time.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] For example, see Figure 1 - Figure 4The present invention is a wire harness welding intelligent robot, comprising a welding platform 1 and a welding robot 11. The top of the welding platform 1 is fixedly connected with two electric telescopic rods 12. The top of the welding platform 1 is provided with two clamping blocks 13. The outer walls of the two clamping blocks 13 are fixedly connected with fixed plates 131.

The top of the welding platform 1 is slidably connected with a wire harness 14. The top of the welding platform 1 is fixedly connected with a placement plate 15. The parts contained in the two clamping blocks 13 are the same.

[0037] The suction mechanism 2 includes a sliding ring 21 slidably connected to the inner wall of the clamping block 13, a spring connecting rod 22 slidably connected to the inner wall of the clamping block 13, a side wall of the spring connecting rod 22 is fixedly connected to the side wall of the sliding ring 21, nine suction cups 23 are fixedly connected to the side wall of the clamping block 13, a push plate 24 is slidably connected to the inner wall of the clamping block 13, a spring return rod 241 is fixedly connected to the side wall of the push plate 24, an outer wall of the spring return rod 241 is slidably connected to the outer wall of the clamping block 13, and a dust removal component 4 is provided on the outer wall of the clamping block 13;

[0038] The blocking mechanism 3 includes a fixed arc block 31 fixedly connected to the inner wall of the clamping block 13, a sliding arc block 32 slidably connected to the inner wall of the clamping block 13, an arc spring 33 fixedly connected to the side wall of the sliding arc block 32, three connecting grooves 34 are provided on the inner walls of the fixed arc block 31 and the sliding arc block 32, and a guide assembly 5 is provided on the outer wall of the clamping block 13. The staff places the wire harness 14 to be welded on the welding table 1, inserts the multiple wires in the wire harness 14 into the placement plate 15, and then starts the electric telescopic rod 12 to extend, pushing the fixed plate 131 toward the wire harness The clamping block 13 moves in the direction of the beam 14, driving the clamping block 13 to move, so that the two clamping blocks 13 are close to each other. When the clamping block 13 moves, the spring connecting rod 22 will move. As the clamping block 13 continues to move, the two spring connecting rods 22 will contact each other, so that the two spring connecting rods 22 are squeezed against each other, so that the two spring connecting rods 22 are separated from each other, driving the sliding ring 21 to move, and at the same time, the two spring connecting rods 22 accumulate resilience. At this time, since the connecting grooves 34 on the fixed arc block 31 and the sliding arc block 32 are intertwined and not yet connected, when the sliding ring 21 moves, it will make the sliding ring Negative pressure is generated on one side of the moving ring 21 close to the fixed arc block 31. As the clamping block 13 continues to move, the two push plates 24 will also contact each other. At this time, the suction cup 23 will also contact the surface of the wire harness 14. When the two push plates 24 contact each other, the two push plates 24 will squeeze each other, so that the two push plates 24 move away from each other. At the same time, the spring return rod 241 accumulates resilience. When the push plates 24 move away from each other, the push plates 24 will push the sliding arc block 32 to slide in the clamping block 13, so that the sliding arc block 32 moves, squeezing the arc spring 33. When the sliding arc block 32 moves , the connecting groove 34 on the fixed arc block 31 will be connected with the connecting groove 34 of the sliding arc block 32, and the negative pressure will be transmitted to the suction cup 23 through the connecting groove 34, so that the suction cup 23 can adsorb the wire harness 14 and complete the clamping of the wire harness 14. After the clamping is completed, the welding robot 11 is started to weld the wire harness 14. By adsorbing and clamping the wire harness 14, a uniform adsorption force is provided, which effectively prevents the wire harness 14 from being subjected to excessive squeezing force during the clamping process, avoids the misalignment of the wires inside the wire harness 14, and affects the position of the wires, so that the welding robot 11 can accurately locate the position of the wires in the wire harness 14.

[0039] For example 2, please refer to Figure 5 - Fig. 9The present invention is a wire harness welding intelligent robot. On the basis of the first embodiment, the dust removal component 4 includes a fixed ring 41 fixedly connected to the outer wall of the spring connecting rod 22, two inclined rods 42 are fixedly connected to the side wall of the fixed ring 41, and two fixed frames 43 are fixedly connected to the outer wall of the clamping block 13. The inner walls of the two fixed frames 43 are slidably connected with spring extrusion plates 431. When the two spring connecting rods 22 move away from each other, the fixed ring 41 will also be driven to move, so that the inclined rod 42 moves. As the inclined rod 42 continues to move, the inclined surface of the inclined rod 42 will contact the inclined surface of the top of the spring extrusion plate 431, thereby squeezing the spring extrusion plate 431, causing it to drop, accumulating resilience, and at the same time, squeezing the gas in the fixed frame 43.

[0040] The dust removal assembly 4 also includes an inclined panel 432 fixedly connected to the bottom of the spring extrusion plate 431. The inner walls of the two fixed frames 43 are slidably connected with the spring inclined panels 433. The bottoms of the two fixed frames 43 are connected with gas pipes 44. At this time, the squeezed gas will be blocked by the spring inclined panels 433, so the gas pressure will increase. When the spring extrusion plate 431 descends, the inclined panel 432 will also be driven to descend, so that the inclined surface of the inclined panel 432 will contact the inclined surface of the spring inclined panel 433, thereby squeezing the spring inclined panel 433.

[0041] The dust removal assembly 4 also includes two air collecting frames 45 fixedly connected to the outer wall of the clamping block 13. The side walls of the two air collecting frames 45 are connected to the outer wall of the air pipe 44. The two air collecting frames 45 are connected to three jet pipes 46 on the side away from the air pipe 44. The spring inclined panel 433 moves toward the air collecting frame 45, thereby eliminating the obstruction to the gas. The gas will enter the air pipe 44, be transported into the air collecting frame 45 through the air pipe 44, and be dispersed into the jet pipe 46 through the air collecting frame 45. At this time, since the suction cup 23 is not in contact with the wire harness 14, the gas will be sprayed toward the wire harness 14 through the jet pipe 46 to remove the dust attached to the wire harness 14.

[0042] The guide assembly 5 includes a sliding ring 51 slidably connected to the outer wall of the clamping block 13, and the tops of the two spring extrusion plates 431 are fixedly connected to a connecting frame 52. The outer wall of the clamping block 13 is rotatably connected to two rotating frames 53. The inner walls of the two rotating frames 53 are slidably connected to the side walls of the connecting frame 52, and the side walls of the sliding ring 51 are slidably connected to the inner walls of the two rotating frames 53. When the spring extrusion plate 431 descends, it will also drive the connecting frame 52 to descend, allowing the rotating frame 53 to descend, causing the rotating frame 53 to rotate, causing the rotating frame 53 to tilt, and pulling the sliding ring 51 to move toward the fixed frame 43.

[0043] The guide assembly 5 also includes four racks 54 fixedly connected to the outer wall of the sliding ring 51, two gear rods 55 are rotatably connected to the inner walls of the two gas collecting frames 45, the side walls of the four racks 54 are meshed and connected to the outer walls of the gear rods 55, the outer walls of the four gear rods 55 are fixedly connected to the fan-shaped frames 551, and the side walls of the two gas collecting frames 45 are fixedly connected to two fixing rings 552;

[0044] Among them, the inner walls of the four fixed rings 552 are fixedly connected with clockwork springs 553, and the inner walls of the four clockwork springs 553 are fixedly connected to the outer wall of the gear rod 55, driving the rack 54 to move, allowing the rack 54 to mesh with the gear rod 55, driving the gear rod 55 to rotate, allowing the fan-shaped frame 551 to rotate, and the clockwork spring 553 to rotate, so that the clockwork spring 553 is tightened and accumulates rebound force. When the gas in the fixed frame 43 enters the gas supply pipe 44, the rack 54 will separate from the gear rod 55, the limit on the clockwork spring 553 will disappear, the rebound force of the clockwork spring 553 will be released, and the fan-shaped frame 551 will rotate, thereby guiding the airflow entering the gas collecting frame 45.

[0045] The guide assembly 5 also includes three air injection pipes 56 connected to the inner wall of the clamping block 13. The inner walls of the three air injection pipes 56 are all rotatably connected to a blocking ring 561. The side wall of the sliding ring 51 is fixedly connected to three fixing rods 562. The outer wall of the clamping block 13 is fixedly connected to three spring blocks 563. When negative pressure is generated on the side of the sliding ring 21 close to the fixed arc block 31, the sliding ring 21 will also squeeze the gas on the side away from the fixed arc block 31, and the squeezed gas will enter the air injection pipe 56. The gas in the second tube 56 is blocked by the blocking ring 561, so that the gas generates high pressure. At the same time, when the sliding ring 51 moves toward the fixed frame 43, it will also drive the fixed rod 562 to move, so that the fixed rod 562 contacts with the blocking ring 561, pushes the blocking ring 561 to rotate, and squeezes the spring block 563. When the blocking ring 561 rotates, it will cancel the obstruction to the gas in the second jet tube 56, and let the high-pressure gas spray toward the surface of the clamping block 13 close to the wiring harness 14 and the suction cup 23, thereby accelerating its cooling speed.

[0046] There is no limitation on the number of the above components, and relevant technicians in the field can freely set them according to actual needs, as long as the above components are installed at the connection positions of the corresponding components.

[0047] The method of using the wire harness welding intelligent robot includes the following steps:

[0048] S1: adsorption clamping;

[0049] S2: dust removal;

[0050] S3: Airflow guidance.

[0051] A specific application of this embodiment is as follows: when the present invention is used, the staff places the wire harness 14 to be welded on the welding table 1, inserts the multiple wires in the wire harness 14 into the placement plate 15, and then starts the electric telescopic rod 12 to extend, pushes the fixed plate 131 to move in the direction of the wire harness 14, drives the clamping block 13 to move, and makes the two clamping blocks 13 approach each other. When the clamping block 13 moves, it will drive the spring connecting rod 22 to move. As the clamping block 13 continues to move, the two spring connecting rods 22 will contact each other, so that the two spring connecting rods 22 are squeezed against each other, and the two spring connecting rods 22 are separated from each other, driving the sliding ring 21 to move, and at the same time, the two spring connecting rods 22 accumulate rebound force. At this time, since the connecting grooves 34 on the fixed arc block 31 and the sliding arc block 32 are intertwined and not yet connected, when the sliding ring 21 moves, negative pressure will be generated on the side of the sliding ring 21 close to the fixed arc block 31. As the clamping block 13 continues to move, the two pushing plates 24 will also contact each other. At this time, the suction cup 2 3 will also contact the surface of the wire harness 14. When the two push plates 24 contact each other, the two push plates 24 will squeeze each other, so that the two push plates 24 move away from each other. At the same time, the spring return rod 241 accumulates resilience. When the push plates 24 move away from each other, the push plates 24 will push the sliding arc block 32 to slide in the clamping block 13, so that the sliding arc block 32 moves and squeezes the arc spring 33. When the sliding arc block 32 moves, the connecting groove 34 on the fixed arc block 31 and the sliding arc block 32 are connected. When the connecting groove 34 is connected, the negative pressure will be transmitted to the suction cup 23 through the connecting groove 34, so that the suction cup 23 can absorb the wire harness 14 and complete the clamping of the wire harness 14. After the clamping is completed, the welding robot 11 is started to weld the wire harness 14. By adsorbing and clamping the wire harness 14, a uniform adsorption force is provided, which effectively prevents the wire harness 14 from being subjected to excessive squeezing force during the clamping process, avoids the misalignment of the wires inside the wire harness 14, and affects the position of the wires, so that the welding robot 11 can accurately locate the position of the wires in the wire harness 14;

[0052] Secondly, when the two spring connecting rods 22 move away from each other, the fixed ring 41 is also driven to move, allowing the inclined rod 42 to move. As the inclined rod 42 continues to move, the inclined surface of the inclined rod 42 will contact the inclined surface at the top of the spring extrusion plate 431, thereby squeezing the spring extrusion plate 431 to make it fall, accumulating resilience, and at the same time, squeezing the gas in the fixed frame 43. At this time, the squeezed gas will be blocked by the spring inclined plate 433, so the pressure of the gas will increase. When the spring extrusion plate 431 falls, it will also drive the inclined plate 432 to fall, allowing the inclined surface of the inclined plate 432 to contact the spring inclined plate 433. The inclined surface contacts and squeezes the spring inclined plate 433, so that the spring inclined plate 433 moves toward the gas collecting frame 45, thereby removing the obstruction to the gas, and the gas will enter the gas delivery pipe 44, and be transported into the gas collecting frame 45 through the gas delivery pipe 44, and dispersed into the air injection pipe 46 through the gas collecting frame 45. At this time, since the suction cup 23 is not in contact with the wire harness 14, the gas will be sprayed toward the wire harness 14 through the air injection pipe 46, and the dust attached to the wire harness 14 is removed, effectively preventing the dust attached to the wire harness 14, which may affect the close fit between the suction cup 23 and the wire harness 14, and affect the adsorption effect of the suction cup 23;

[0053] Secondly, when the spring extrusion plate 431 descends, it will also drive the connecting frame 52 to descend, so that the rotating frame 53 descends, the rotating frame 53 rotates, and the rotating frame 53 tilts, pulling the sliding ring 51 to move toward the fixed frame 43, driving the rack 54 to move, so that the rack 54 meshes with the gear rod 55, driving the gear rod 55 to rotate, so that the fan-shaped frame 551 rotates, and the spring spring 553 rotates, so that the spring spring 553 is tightened and accumulates resilience. When the gas in the fixed frame 43 enters the gas pipe 44, The rack 54 will separate from the gear rod 55, and the limit on the clockwork spring 553 will disappear. The resilience of the clockwork spring 553 will be released, allowing the fan-shaped frame 551 to rotate, thereby guiding the airflow entering the gas collecting frame 45, and the airflow will be attracted to the top and bottom jet pipes 46, so that the gas entering the three jet pipes 46 is evenly distributed, effectively preventing most of the gas from being ejected from the middle jet pipe 46, affecting the removal of dust on the surface of the wire harness 14, and may make it difficult to remove dust in some areas;

[0054] Secondly, when negative pressure is generated on the side of the sliding ring 21 close to the fixed arc block 31, the sliding ring 21 will also squeeze the gas on the side away from the fixed arc block 31, and the squeezed gas will enter the injection pipe 2 56 and be blocked by the blocking ring 561, so that the gas will generate high pressure. At the same time, when the sliding ring 51 moves toward the fixed frame 43, it will also drive the fixed rod 562 to move, so that the fixed rod 562 contacts the blocking ring 561, and push the blocking ring 561 to rotate, squeezing the spring block 563. When the blocking ring 561 rotates, it will take Eliminate the obstruction of the gas in the jet pipe 56, and let the high-pressure gas spray toward the surface of the clamping block 13 close to the wire harness 14 and the suction cup 23, so as to accelerate the cooling speed, and effectively prevent the high temperature generated during the welding of the wire harness 14 from being transferred to the clamping block 13. Moreover, since the welding speed of the welding robot 11 is relatively fast, the temperature of the clamping block 13 and the suction cup 23 may continue to rise and it is difficult to effectively cool down, resulting in temperature accumulation, which may cause the suction effect of the suction cup 23 on the wire harness 14 to deteriorate, which helps the suction cup 23 to maintain a good adsorption effect for a long time.
